🌙 CHAPTER 1 — “Room 403 Agreement”

The dormitory hallway smelled faintly of clean detergent and summer humidity.

Room 403 was at the end.

The last room.

The quiet one.

Or at least—it was supposed to be.

Ren Kisaragi stood in front of the door longer than necessary.

His hand hovered near the handle.

Then dropped.

Then hovered again.

Behind him, the dorm supervisor cleared his throat.

“You’ll be sharing this room starting this semester.”

Ren didn’t respond immediately.

“…I understand.”

His voice was calm.

Too calm.

Like he was trying to convince himself more than anyone else.

The door slid open.

And that was when Haruki Amamiya looked up.

White hair slightly messy.

A half-folded shirt in his hands.

And a smile so bright it looked completely out of place in a shared dorm room.

“Oh—new roommate?”

His tone was light.

Friendly.

Almost too friendly.

Ren stared for exactly two seconds longer than socially acceptable.

Then stepped inside.

“…Yes.”

That was all.

Haruki blinked.

Then smiled wider.

“Nice to meet you!”

He bowed slightly.

Too casually.

Too energetically.

“I’m Haruki Amamiya. Second-year.”

Pause.

Then, with a playful tilt of his head:

“So… are you gonna do anything weird in here?”

Ren froze.

“…What.”

Haruki laughed.

“I mean like—bringing strangers in at night, loud music, illegal pet reptiles, that kind of thing.”

Ren looked at him like he was mentally unstable.

“I will not.”

“Good,” Haruki said instantly. “Me neither.”

A silence settled.

Not uncomfortable.

Just unfamiliar.

Ren placed his bag down neatly.

Organized.

Precise.

Haruki watched him.

Then said casually:

“I like quiet roommates.”

Ren didn’t respond.

Haruki leaned slightly closer.

“…You’re quiet, aren’t you?”

Ren finally looked at him directly.

“Yes.”

Another pause.

“…Good.”

Haruki smiled again.

Like he had just decided something.

The Privacy Promise

That evening, Haruki suddenly pulled out his phone.

“Hey.”

Ren looked up.

“…What.”

Haruki grinned.

“Let’s make a rule.”

He pointed the camera between them.

“A privacy promise video.”

Ren frowned immediately.

“I do not want to be recorded.”

“Relax, it’s just for us.”

“That is what people say before disasters.”

Haruki laughed.

“I swear I won’t post it.”

Ren stared at him for a long moment.

Then sighed.

“…Fine.”

The camera started recording.

Haruki leaned in.

“Room 403 agreement!”

Ren looked deeply unamused.

Haruki continued:

“We respect each other’s privacy.”

Ren nodded slightly.

“No unnecessary interference.”

“Yes!” Haruki said.

A pause.

Then softer:

“…And no falling in love with each other.”

Ren froze.

“…That was unnecessary.”

Haruki laughed loudly.

“I’m joking, I’m joking.”

But neither of them smiled at the same time.

The video ended.

Haruki stretched.

“Alright. Welcome home, roommate.”

Ren looked at him for a long moment.

Then quietly:

“…Thank you.”

Haruki blinked.

Then smiled slightly softer than before.

“Yeah. Anytime.”

That night, neither of them realized—

this was the beginning of something neither privacy rules nor promises would survive.

🌙 CHAPTER 2 — “Don’t Do Anything Gay in Here”

Room 403 was too quiet.

Not peaceful quiet.

Awkward quiet.

The kind that makes you suddenly aware of every small sound:

paper shifting

footsteps outside

a fridge humming like it knows something you don’t

Ren sat on his bed, perfectly straight-backed, staring at his schedule book.

Haruki, on the other side of the room, was lying upside down on his own bed like gravity was optional.

“…So,” Haruki said casually, “what year are you?”

Ren didn’t look up.

“First.”

“Ohhh,” Haruki dragged the word out like it was interesting. “So I’m your senpai.”

“Yes.”

A pause.

Then Haruki sat up slightly.

“Respect me.”

Ren finally looked at him.

“I am not required to respect you.”

Haruki gasped dramatically.

“Rude.”

Silence again.

Ren returned to his notes.

Haruki, however, was clearly not done existing loudly.

“So like,” Haruki said, rolling onto his side, “what do you usually do in dorms? You know… like normal roommate stuff.”

Ren paused.

“…Study.”

“That’s it?”

“Yes.”

Haruki blinked.

“That’s depressing.”

“It is efficient.”

Haruki suddenly sat up fully.

Eyes sparkling with curiosity.

“Okay wait.”

Ren tensed slightly.

“What.”

Haruki pointed at him.

“Don’t do anything gay in here.”

Dead silence.

Ren slowly lowered his pen.

“…What did you just say.”

Haruki leaned forward, completely serious now.

“I said—don’t do anything gay in here.”

Ren stared at him.

For a long moment.

Then:

“…I was not planning to.”

Haruki nodded.

“Good. Because I also wasn’t planning to.”

Another pause.

Then Haruki added:

“…Unless it happens by accident.”

Ren immediately stood up.

“I am moving rooms.”

Haruki burst out laughing.

“WAIT I WAS KIDDING!”

First Real Misunderstanding

That night, Ren noticed something strange.

Haruki talked to him too easily.

Too comfortably.

Like they were already familiar.

Like he didn’t respect personal space boundaries at all.

He:

leaned too close when speaking

smiled too often

asked too many questions

remembered things Ren didn’t expect anyone to care about

“Do you like sweet drinks or bitter ones?”

“…Bitter.”

“Ah. That fits you.”

“…What does that mean.”

“Nothing bad!”

Ren did not trust “nothing bad.”

The Beginning of the Habit

Later that night, Haruki came back from somewhere outside.

He dropped a drink on Ren’s desk.

“Here.”

Ren looked at it.

“…What is this.”

“Coffee. You said you like bitter.”

“I did not ask for this.”

“I know.”

That answer should have been alarming.

But Haruki just smiled like it was normal.

Ren didn’t touch it immediately.

Haruki noticed.

“…You don’t trust me?”

Ren hesitated.

Then honestly:

“No.”

Haruki blinked.

Then smiled again—but slightly smaller this time.

“…Fair.”

He sat down across from Ren.

This time quieter.

Less loud energy.

“Okay,” he said, “then I’ll earn it.”

Ren frowned slightly.

“…That is unnecessary effort.”

Haruki tilted his head.

“Maybe. But I want to.”

Silence.

Ren didn’t know why that answer made him uneasy.

Ending Scene

Later, lights off.

Room dark except for hallway glow under the door.

Ren lay in bed.

Haruki too.

Quiet.

Still.

Then—

soft voice:

“…Hey, Ren.”

“…What.”

A pause.

Then Haruki, softer than before:

“Don’t worry. I’m not weird.”

Ren stared at the ceiling.

“…You are already weird.”

Haruki laughed quietly.

“Okay. Fair.”

Another pause.

Then:

“…Goodnight, roommate.”

Ren hesitated.

Then, very quietly:

“…Goodnight.”

And for the first time—

Room 403 stopped feeling like two strangers sharing space.

And started feeling like something waiting to happen.

🌙 CHAPTER 3 — “The Agency Directive”

Spring arrived in Tokyo like it didn’t care who was already struggling.

Too bright. Too loud. Too full of people pretending they had everything figured out.

Haruki didn’t.

Ren definitely didn’t.

And somehow—that was exactly when everything got worse.

The Call

Haruki’s phone rang during lunch.

He stared at the screen for a second too long.

“…I’m going to regret this,” he muttered.

Then answered.

“Hello?”

A sharp voice came through immediately.

“Amamiya Haruki.”

Haruki straightened instinctively.

“…Yes.”

“We need you at headquarters.”

Pause.

“…Now?”

“Yes.”

Click.

The line went dead.

Ren watched him from across the table.

“…Trouble?”

Haruki forced a smile.

“Nope.”

A pause.

Then, softer:

“…Probably yes.”

The Agency Room

The company building was too clean.

Too white.

Too expensive-looking.

Haruki sat in a meeting room with three executives and a folder placed in front of him.

He already knew this was going to be bad.

“You’ve been selected for a new promotional strategy,” one of them said.

Haruki blinked.

“…A what?”

The folder slid toward him.

He opened it.

And froze.

Inside:

Photos.

Clips.

Fan edits.

Comments.

All centered on him and Ren.

Haruki stared.

“…Why is my roommate in here.”

The executive didn’t blink.

“Your current public engagement metrics have increased significantly whenever you are seen with him.”

Haruki slowly closed the folder.

“…That’s not a sentence I like hearing.”

Another voice joined.

“We want you to maintain a ‘close public relationship narrative.’”

Haruki frowned.

“…You mean fake dating.”

Silence.

That was the confirmation.

Haruki’s Immediate Reaction

“No.”

Immediate.

Sharp.

Final.

“I’m not doing that.”

The room didn’t react emotionally.

Just practically.

“You will not be forced,” the executive said. “But it is highly recommended for career stability.”

Haruki leaned back.

“…I hate this job sometimes.”

But Then They Said His Name

“One condition,” the executive added.

Haruki narrowed his eyes.

“…What.”

“Your roommate will also be approached.”

Silence.

That landed differently.

Haruki’s expression changed immediately.

“…Don’t involve him.”

“We will only suggest.”

“That’s still involvement.”

A pause.

Then softer:

“…He’s not part of this world.”

And for a moment—

Haruki realized something uncomfortable.

He wanted to protect Ren more than he wanted to protect himself.

Back at Room 403

Ren noticed immediately when Haruki came back.

“…You look different.”

Haruki dropped onto his bed.

“I had a corporate horror experience.”

“That is not a category.”

“It is now.”

Ren watched him.

“…What happened.”

Haruki hesitated.

Then:

“…Nothing.”

Too fast.

Too fake.

Ren frowned.

“You are lying.”

Haruki groaned.

“I hate how good you are at reading me.”

Silence.

Then Haruki sat up.

“…Can I ask you something weird?”

Ren already looked suspicious.

“…Depends.”

Haruki exhaled.

“Would you ever date someone… for appearance?”

Ren stared at him.

“…No.”

Immediate.

No hesitation.

“Why would anyone do that.”

Haruki looked away slightly.

“…Good answer.”

But something in his expression didn’t relax.

The First Lie Begins

That night, Haruki made a decision.

Not because he wanted to lie.

But because he didn’t want Ren pulled into something that could hurt him.

So when the agency called again—

Haruki said:

“…Fine.”

Fake Dating Proposal

The next meeting was worse.

“Public pairing narrative,” they called it.

Haruki called it what it was in his head:

Damage control.

“We suggest you present yourselves as dating publicly,” they said.

Haruki laughed once.

“…You’re insane.”

“It is beneficial for both popularity and stability.”

Haruki leaned forward.

“…And what does the other person get out of this.”

A pause.

“…Exposure.”

Haruki’s expression darkened slightly.

“Yeah. No.”

But then—

they showed him something.

A draft campaign.

His and Ren’s names together.

Projected media attention.

Pressure building.

And Haruki thought about Ren.

Quiet Ren.

Careful Ren.

The one who didn’t even like being looked at too long.

So Haruki did something he hated himself for later.

“…I’ll consider it.”

The First Fake Moment

Back in Room 403, Haruki acted normal.

Too normal.

Almost carefully normal.

Which made Ren more suspicious than anything else.

“…You’re avoiding me,” Ren said suddenly.

Haruki froze.

“…I’m not.”

“You are.”

Silence.

Haruki laughed awkwardly.

“I’m just tired.”

Ren stared at him for a long moment.

“…That is also a lie.”

Haruki’s chest tightened.

Because it was.

The Ren-chan Voice Appears

Later that evening, Haruki finally cracked under stress.

Ren was cooking instant noodles.

Haruki walked in behind him.

And without thinking—

softened completely.

“…Ren-chan.”

Silence.

Ren froze.

Slowly turned.

“…What did you call me.”

Haruki blinked.

“…I didn’t mean—”

But it was too late.

The tone had already happened.

Too soft.

Too affectionate.

Too familiar.

Ren stared at him.

“…Do not call me that.”

Haruki panicked slightly.

“I won’t. I swear.”

But even as he said it—

he realized something terrifying.

That voice didn’t feel forced.

It felt natural.

Ending Scene

That night, Haruki couldn’t sleep.

Ren was already asleep.

Quiet.

Stable.

Safe-looking.

Haruki stared at the ceiling.

Thinking:

If I agree to this fake thing… will it change how he sees me?

A pause.

Then quieter:

Or will it protect him?

And in the darkness of Room 403—

Haruki made the worst decision he could make for himself.

But maybe the best one for Ren.

He whispered:

“…I’ll do it.”

And somewhere across the room,

Ren shifted slightly in his sleep—

completely unaware that the shape of their relationship had just started changing forever.
